Stus-List Electrical Question

The light I am talking about is the one 1/2 up the front of the mast 
just above the spreaders....not the one on the top of the mast seen 360 
degrees......I was told the one on the front of the mast is longer a 
legal requirement but the one on the top of the mast is a legal 
requirement when motoring or motor sailing.

Am I correct?
